Question: A binary mixture of benzene(1) and toluene(2) is flashed to 75 kPa and 90C. Analysis of the effluent liquid and vapor streams from the separator

A binary mixture of benzene(1) and toluene(2) is flashed to 75 kPa and 90°C. Analysis of the effluent liquid and vapor streams from the separator yields: x1 = 0.1604 and y1 = 0,2919.
An operator remarks that the product streams arc "'off-spec," and you are asked to diagnose the problem.
(a) Verify that the exiting streams are not in binary equilibrium.
(b) Verify that an air Leak into (he separator could be the cause.
